Because laser welding is a fast and uneven thermal cycle process. A large temperature gradient appears near the weld, and different degrees of residual stress and deformation occur in the welded structure, which are important factors affecting the quality and performance of the welded structure. Since the fundamental cause of laser welding stress and deformation is uneven heating and cooling during welding, the study of laser welding temperature field is the premise of laser welding stress and strain analysis. Therefore, it is of great practical significance to accurately understand the laser welding temperature field.
In the past, the analysis of the temperature field and stress-strain field of laser welding was carried out by measuring the collected data and performing quantitative analysis. Due to limitations in experimental conditions, etc., the accuracy of the data obtained is not high, and a lot of manpower, material resources and time are wasted. Although these problems can be quantitatively calculated by analytical methods that solve some specific differential equations, only in very simple cases. And many simplifying assumptions make it possible to obtain analytical solutions for the closure of these equations. There are many welding problems in the two chambers, and the boundary conditions are very complicated. It is very difficult to solve such differential equations by analytical methods. In today's development of high-speed electronic computers, numerical simulation methods are mostly used.
